echo out $_SESSION data

I have a bunch of data in an array which has been collected in a session. I am able to print_r this and show all the contents but I am struggling to show the product name, id, image etc.

I am showing the using:

<?php
echo '<pre>';
print_r($_SESSION);
echo '</pre>';
?>

It prints out everything I need but not in the format I require. So I know it is collecting my data and storing it in the array. I have set the data in another files like so:

if (isset($_POST['Submit'])) { 
    $_SESSION['product_img'][] = $_POST['product_img'];
    $_SESSION['product_id'][] = $_POST['product_id'];
    $_SESSION['product_name'][] = $_POST['product_name'];
    $_SESSION['product_price'][] = $_POST['product_price'];
    $_SESSION['product_sku'][] = $_POST['product_sku'];
    $_SESSION['product_description'][] = $_POST['product_description'];
}

And it is all of the above I want to output.

**Either you stick with your proposal : $_SESSION['...'][] **

if (isset($_POST['Submit'])) { 
    $_SESSION['product_img'][] = $_POST['product_img'];
    $_SESSION['product_id'][] = $_POST['product_id'];
    $_SESSION['product_name'][] = $_POST['product_name'];
    $_SESSION['product_price'][] = $_POST['product_price'];
    $_SESSION['product_sku'][] = $_POST['product_sku'];
    $_SESSION['product_description'][] = $_POST['product_description'];
}

and format it like so:

foreach($_SESSION as $elements)
{
    foreach($elements as $element) {
        echo $element . '<br />';
    }
}

Or use this other method:

if (isset($_POST['Submit'])) { 
    $_SESSION['product_img'] = $_POST['product_img'];
    $_SESSION['product_id'] = $_POST['product_id'];
    $_SESSION['product_name'] = $_POST['product_name'];
    $_SESSION['product_price'] = $_POST['product_price'];
    $_SESSION['product_sku'] = $_POST['product_sku'];
    $_SESSION['product_description'] = $_POST['product_description'];
}

and format it like so:

foreach($_SESSION as $element)
{
    echo $element . '<br />';
}

A simple way to output this as HTML is to use a foreach loop, which goes through each item in the array.

To make things easier, I would suggest changing your POST code so that each item is a single array, like so.

if (isset($_POST['Submit'])) { 
    $_SESSION['products'][] = array(
        'img' => $_POST['product_img'],
        'id' => $_POST['product_id'],
        'name' => $_POST['product_name'],
        'price' => $_POST['product_price'],
        'sku' => $_POST['product_sku'],
        'description' => $_POST['product_description']
    );
}

Now you can iterate through $_SESSION['products'] and get the information for each product in the session. For example:

foreach ($_SESSION['products'] as $product) {
    $name = $product['name'];
    $id = $product['id'];
    $price = $product['price'];
    $img = $product['img'];
    $sku = $product['sku'];
    $description = $product['description'];

    echo "<h1>Product: $name</h1>";
    echo "<p>Price: $price | ID: $id</p>";
    echo "<img src='$img'>";
    echo "<p>$description</p>";
    echo "<hr />";
}
